Well, i have installed Oracle8i for Linux. for GUI configuration programs, it uses jre (jdk1.1.6) that i have installed too. runInstaller and dbassist work fine but netasst doesn't. I have launch netasst with java (not jre) and it said to me :

libnjni8.so: cannot read file data: Aucun fichier ou répertoire de ce type (libnjni8.so) Error loading native jni library.
java.lang.UnsatisfiedLinkError: getOracleHome

        at oracle.net.asst.container.NetProperties.<init>(NetProperties.java:48)
        at oracle.net.asst.container.NetContainer.<init>(NetContainer.java:243)
        at oracle.net.asst.container.NetApplication.init(NetApplication.java:51)
        at oracle.sysman.emSDK.client.appContainer.WebApplication.main(WebApplication.java:2551)

so i took a look to libnjni8.so but it was an empty file. So the question is :

where could i find libnjni8.so for Linux ? (in ELF little-indian).

the goal is to install TCP/IP listener for my database. Perhaps you know a configuration "by hands" ?

you could take a look at my files :

in the following [hostname, dbname, machine_address, user and passwd are good because we test it on sqlplus] but are not given here because it is not necessary.

listener.ora :

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521))
(PROTOCOL_STACK =

        (PRESENTATION = TTC)
        (SESSION = NS)
      )

)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
(PROTOCOL_STACK =

        (PRESENTATION = TTC)
        (SESSION = NS)
      )

)
)

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
(GLOBAL_DBNAME = db_name)
(ORACLE_HOME = /u01/app/oracle/product/8.1.5)
(SID_NAME = db_name)

    )
  )

tnsnames.ora :

db_name =
  (DESCRIPTION =
    (ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521))
    )
    (CONNECT_DATA =
(SERVICE_NAME = db_name)

    )
  )

sqlnet.ora :

SQLNET.EXPIRE_TIME = 0 SQLNET.CRYPTO_SEED = <a crypto-seed that i do not need to show here>

i have put in my /etc/services:

listener 1521/tcp # Net8 listener

and when i execute lsnrctl start :

$ lsnrctl start

but i could not at all make a connection with my database :

this instruction :

conn = DriverManager.getConnection("jdbc:oracle:thin:@(description=(address=(host=10.3.0.45)(protocol=tcp) (port=1521))(connect_data=(sid=db_name)) )",user,passwd);

or this one :

conn = DriverManager.getConnection("jdbc:oracle:thin:@machine_address:1521:db_name",user,passwd);

returns the same error message :

No more data to read from socket
Exception in thread "main" java.lang.NullPointerException

at Temp.main(Compiled Code)

Could someone help me ???
